is it possible to use an EMulex QD32 Controller (Qbus)

Why not?
I asked a friend and he told me that the bandwith of
the bus could be
drifferent.
You mean the bus with, that is not the same as the bandwith?
Perhaps he means that the /23 uses only 18 bit. The first (low end) QBus
implementations used only 18 bits for address space. The QD32 can use
all 22 bits of a "full blown" QBus. AFAIK you can jumper the QD32 to use
only 18 bit adressing. Sorry I have my QD32/33 manual not at my hands...
